A baseball player went up to bat 250

times in a season. He hit the ball 100
times. Find the rate of balls hit to times at bat. Express as a simplified fraction.

The rate of balls hit to times at bat is given by the fraction:

(100/250)

To simplify, we can divide both the numerator and denominator by their greatest common divisor, which is 50:

(100/250) = (2/5)

Therefore, the rate of balls hit to times at bat is 2/5.
